Antigravity, Insforge and TestSprite app tutorial

This tutorial follows a prompt-based workflow for building a Next.js SaaS application with Antigravity, Insforge and TestSprite. The presenter starts with a blank project, uses a reference screenshot to generate the interface, and embeds a Spline 3D background. Screenshot prompts guide layout fixes and animation changes.

The backend setup requires an Insforge account, a project and CLI authorization. The presenter uses its installed skills to request authentication, then demonstrates signup with email verification. A chat modal connects to GPT-4o through Insforge's model gateway. This is a hosted provider workflow; the tutorial does not demonstrate running model inference on the viewer's hardware.

TestSprite connects through MCP configuration and an API key. Testing requires a running development server, its localhost port, valid login credentials where needed, and a specification document or README. The presenter reports seven passes and four failures across 11 frontend tests, including access to protected pages without signing in. After a prompted fix, the rerun has nine passes, one failure and one blocked test. Email verification prevents the tool from completing signup.

The final sections cover deployment through Insforge and connecting TestSprite to GitHub for tests on pushes and pull requests. The reported results leave a failed test unresolved, so they do not establish that the app is ready for production.
